Texas Instruments SIMPLE SWITCHER® LM2678SDX-3-3 is a high-efficiency, monolithic synchronous buck switching regulator. This device offers a fixed 3.3V output voltage with a 5A maximum output current, operating from an input voltage range of 8V to 40V. The internal switch and synchronous rectifier minimize component count, and the high switching frequency of 260kHz allows for smaller inductor and capacitor values, reducing overall solution size and cost. Its robust design is suitable for applications in the industrial, automotive, and consumer electronics sectors. The LM2678SDX-3-3 is supplied in a 14-VSON (5x6) package, featuring an exposed pad for enhanced thermal performance. The operating temperature range is -40°C to 125°C (TJ).
